Quickly learn HDMI 2.1! DP 2.0 will introduce new 

certification, reject standard confusion

Not long ago, HDMI officials inexplicably canceled the HDMI2.0 standard and divided it into a subset of the HDMI2.1 standard. This move has aroused widespread doubts from the outside world, which will undoubtedly cause confusion in the HDMI2.1 standard.

To avoid the same controversy as HDMI 2.1, the Video Electronics Standards Association (VESA) said it will adopt a new certification program to ensure customers can tell whether a cable or device supports the standard.

According to reports, Display Port 2.0 supports Display Port UHBR (Ultra High Bit Rate) data transmission. In order to distinguish the specifications, VESA has introduced new DP40 and DP80 UHBR cables.

Among them, the cable marked with DP40 will support the UHBR10 standard with a total bandwidth of 40Gbps; the cable marked with DP80 will support the UHBR20 standard with a total bandwidth of 80Gbps.

VESA said that full-size Display Port and Mini Display Port cables supporting the DP40 and DP80 standards are already in production, and the first monitors and other devices have passed certification testing and are expected to be available to consumers soon.

The fact that the new standard has different specifications and agreements is actually a good thing for consumers. After all, this is to give consumers the right to choose, and consumers can choose the corresponding products according to their needs.

But the premise is that there needs to be clear certification and identification to distinguish. Thinking that HDMI 2.1 does not do any certification and labeling, and let the product side consciously do the labeling, will undoubtedly only increase the confusion of the standard and make consumers more confused when purchasing.

VESA's choice to do logo certification for DP2.0 is undoubtedly a correct move and deserves praise. Unfortunately, the main application of the DP interface is still in the PC field, and TV users are currently unable to enjoy it.

Although most TV brands still carry the HDMI 2.0 and 2.1 logos, everyone should pay more attention when purchasing, especially pay more attention to some small characters on the product details page.
